CONNECTIONS
CONNECTING POWER
You can power your system using ei-
ther AC power or six D batteries (not
supplied).
Using AC Power
The supplied power cord stored inside
the battery compartment lets you power
the system from a standard AC outlet.
1. While pressing down both tabs on
the battery compartment cover in
the direction of the arrow, pull the
cover down to remove it.
2. Remove the power cord from its
storage area in the battery com-
partment, then replace the cover.
3. Plug the small end of the power
cord into the
AC
jack on the back
of the system. Then plug the cord
into a standard AC outlet.
Cautions:
• To prevent electric shock, one
blade on the power cord’s plug is
wider than the other and the plug
fits only one way. If you cannot
easily insert the plug, turn it over
and try again. Do not force it.
• Always plug the power cord into
the system before you plug it into
a standard AC outlet. Always
unplug it from the AC outlet before
you unplug it from the system.
Installing Batteries
You can power the system with six D
batteries (not supplied). For the best
performance, we recommend alkaline
batteries, such as Cat. No. 23-550.
Cautions:
• Use only fresh batteries of the
required size and type.
• Never leave dead or weak batter-
ies in the system.
• If you do not plan to use the sys-
tem for several days, or if you plan
to power the system using only
AC power, remove the batteries.
• Dispose of batteries promptly and
properly; do not bury or burn
them.
Follow these steps to install batteries.
1. While pressing down both tabs on
the battery compartment cover in
the direction of the arrow, pull the
cover down to remove it.
14-703.fm Page 4 Wednesday, June 30, 1999 4:56 PM

2. Remove the power cord from its
storage area in the battery com-
partment.
3. Install the batteries as indicated
by the polarity symbols (+ and
–
)
marked inside the compartment.
4. Replace the battery compartment
cover.
If the system’s sound becomes weak
or distorted, replace the batteries.
USING HEADPHONES
To listen to the system without disturb-
ing others, plug a pair of stereo head-
phones with a
1
/
8
-inch plug (not
supplied) into the system’s
PHONES
jack. This mutes the system’s speak-
ers. Your local RadioShack store sells
a wide selection of headphones.
Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
• Set the volume to the lowest set-
ting before you begin listening.
After you put on the headphones,
adjust the volume to a comfortable
level.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
level that does not cause discom-
fort might still damage your hear-
ing.
Traffic Safety
Do not wear headphones while oper-
ating a motor vehicle or riding a bicy-
cle. This can create a traffic hazard
and is illegal in some areas.
Even though some headphones are
designed to let you hear some outside
sounds when listening at normal vol-
ume levels, they still present a traffic
hazard.

RECORDING
You can record onto a cassette tape
from the radio, use the built-in micro-
phone to make a live recording, or dub
(copy) from one cassette tape to an-
other.
Notes:
• The recording level is preset.
Adjusting
VOLUME
or
E-BASS
does not affect the recording level.
• Most material on compact discs
and prerecorded tapes is copy-
righted. Unauthorized duplication
of copyrighted material is a viola-
tion of the copyright laws of most
countries and such duplication
may result in fines and/or impris-
onment. Note, however, that in the
United States, it is not a violation
of U.S. copyright laws for a con-
sumer to use an audio recording
device to duplicate musical
recordings for noncommercial
(personal) use.
Recording Tips
• Tape quality greatly affects the
quality of the recording. We rec-
ommend extended-range or low-
noise type 1 regular length (60- or
90-minute) normal-bias cassette
tapes. We do not recommend
long-play cassette tapes such as
C-120s because they are thin and
can easily tangle.
• Before recording, be sure the tape
you are recording on has its
erase-protection tabs in place
(see “Preventing Accidental Era-
sure” on Page 12).

TAPE TIPS
ERASING A CASSETTE
TAPE
To record over a cassette tape, simply
record as usual. The system records
over the previous recording.
You can quickly erase both sides of a
cassette tape using a bulk tape eras-
er, such as Cat. No. 44-232.
PREVENTING
ACCIDENTAL ERASURE
Cassette tapes have two erase-pro-
tection tabs — one for each side.
When a tab is in place, you can record
on that side. To protect a recording
from being accidentally recorded over,
use a screwdriver to remove one or
both of the cassette tape’s erase-pro-
tection tabs. This prevents
RECORD
from being pressed.
If you later decide to record on a tape
side after you have removed the
erase-protection tab for that side,
place a piece of strong plastic tape
over that side’s erase-protection hole.
Be sure you cover only the hole origi-
nally covered by the erase-protection
tab.
Caution:
Removing the erase-protec-
tion tabs does not prevent a bulk eras-
er from erasing a cassette tape.
RESTORING TAPE
TENSION AND SOUND
QUALITY
After you play a cassette tape several
times, the tape might become tightly
wound on the reels. This can cause
playback sound quality to deteriorate.
To restore the sound quality, fast-for-
ward the tape from the beginning to
the end of one side, then completely
rewind it. Then loosen the tape reels
by gently tapping each side of the cas-
sette’s outer shell on a flat surface.
Caution:
Be careful not to damage
the cassette when tapping it. Do not
touch the exposed tape or allow any
sharp objects near the cassette.

CARE AND MAINTENANCE
Your Optimus SCR-63 Extended Bass
AM/FM Stereo Dual-Cassette Record-
er is an example of superior design
and craftsmanship. The following sug-
gestions will help you care for the sys-
tem so you can enjoy it for years.
Keep the system dry. If it
gets wet, wipe it dry immedi-
ately. Liquids can contain
minerals that can corrode
the electronic circuits.
Handle the system gently
and carefully. Dropping it
can damage circuit boards
and cases and can cause
the system to work improp-
erly.
Use and store the system
only in normal temperature
environments. Temperature
extremes can shorten the
life of electronic devices,
damage batteries, and dis-
tort or melt plastic parts.
Keep the system away from
dust and dirt, which can
cause premature wear of
parts.
Wipe the system with a
damp cloth occasionally to
keep it looking new. Do not
use harsh chemicals, clean-
ing solvents, or strong deter-
gents to clean it.
Use only fresh batteries of
the required size and type.
Always remove old or weak
batteries. They can leak
chemicals that can destroy
electronic circuits.
Modifying or tampering with the sys-
tem’s internal components can cause
a malfunction and might invalidate the
system’s warranty and void your FCC
authorization to operate it. If your sys-
tem is not performing as it should,
take it to your local RadioShack store
for assistance.
CLEANING THE TAPE-
HANDLING PARTS
Dirt, dust or particles of the tape’s
coating can accumulate on the tape
heads and other parts that the tape
touches. This can greatly reduce the
performance of the cassette recorder.
Use the following cleaning procedure
after every 20 hours of tape player op-
eration.
1. Remove the batteries and discon-
nect the AC power cord.
2. Open the cassette compartment
doors on Deck 1 and Deck 2.
3. Press
PLAY
on Deck 1 to expose
Deck 1’s tape-handling parts.
14-703.fm Page 13 Wednesday, June 30, 1999 4:56 PM

4. While pressing and holding down
the erase-protection tab sensor
inside Deck 2, press
RECORD
on
Deck 2.
RECORD
and
PLAY
on
Deck 2 both lock down. This
exposes Deck 2’s record/playback
head and erase head.
5. Use a cotton swab dipped in
denatured alcohol or tape head
cleaning solution to clean the
record/play heads, tape guides,
pinch rollers, capstans, and erase
head.
6. When you finish cleaning, press
STOP/EJECT
on Deck 1 and Deck
2, then close both cassette com-
partment doors and reconnect
power.
Your local RadioShack store has a
complete line of cassette deck clean-
ing supplies.
THE FCC WANTS YOU
TO KNOW
Your system might cause TV or radio
interference even when it is operating
properly. To determine whether your
system is causing the interference,
turn off your system. If the interfer-
ence goes away, your system is caus-
ing the interference. Try to eliminate
the interference by:
• Moving your system away from
the receiver.
• Connecting your system to an out-
let that is on a different electrical
circuit from the receiver.
• Contacting your local Ra-
dioShack store for help.
If you cannot eliminate the interfer-
ence, the FCC requires that you stop
using your system.
